Deep Slab, Athabasca -Ramp Route

A large deep slab avalanche released above the standard Ramp Route on Mount Athabasca Saturday July 8 around mid day. The slab was potentially triggered by Serac fall from below the silver horn, pulled down to glacier ice, and ran over 200m wiping out the standard line of ascent for the Silver Horn, Ramp Route, and North Face. A reminder that large avalanches still remain a real threat in the alpine.
